As the release states, LaVine will undergo surgery to repair the ACL at a to-be-determined date after tearing the ligament Friday night against the Detroit Pistons.

This is a huge blow to the third-year player out of UCLA. LaVine, who has improved in each of his three seasons, was really starting to get into a groove and produce on a more consistent basis. Now he’ll have to find that groove again after an extended rehab period.

In 47 games this year, last year’s Slam Dunk champ averaged 18.9 points, three assists and 3.4 rebounds per game for the Timberwolves.
